Improvement in harvesters



AUNITED STATES PATENT OFFICE.4

WORDEN P. FENN, JACOB GEISS, AND JACOB BROSIUS, OF BELLEVILLE, ILL.

lli/I PROVEM ENT IN HARVESTERS.

Specification forming part of Letters Patent No; 410.4127, dated October 27, 1863.

To all whom it may concern:

Be it known that we, WORDEN P. PENN,

JACOB Gmss, and JACOB BRosIUs, of Belleville, in the county of St. Clair and State of Iliinois, have invented certain new and useful Improvements in Harvesting-Machines; andwe do hereby declare the .following to be a full, clear,and exact description of the same,

reference heilig hadv to the annexed drawings,

ject, both of which we will describe; but in this application we will claim one of them only.

One of the plans aforesaid is shown by Fig. 2, which represents the inside of the main frame next to said figure, and consists ot` a segmental plate in the outside edge, whereof a wormcog is cut, in which a worin-screw is made to gear. Said screw is fixed between two lugs, u u, cast on a bracket, C, bolted to the inside' of the frame, as shown. The upper end of said screw is made square, so as to receive a wrench of corresponding form, by means of which it is operated and made to raise or lower the main frame on the segmental plate as a guide, said plate being fitted into a groove made in the .bracket e, which groove or seat is formed by the .hooks H H,\cast on the bracketin the manner shown. The said segmental plate ha-ving the hub D made on its inside iace, in which one end of the main shaft has its bearing, the frame will ofcourse be raised or lowered, according as the screw is turned one way or the other. After the main4 frame has been adjusted said segmental plate is held in the desired position by means of one y or more bolts, which pass through the bracket l piece of the main frame. 11n this figure the segmental plate a is secured to the frame Aby means of the bracket e and bolts in the same manner as in Fig. 2.' 'lhe only difference be- Ytween the two plans is in the manner of raising and lowering the frame, the platein Fig. 3"

being operated by a piniomf, which gears'in corresponding 'cogs cut in the convexed'edge of the plate, a wrench being applied to the square end r of the pinion-shaft to operate it.

Our improvements consist, second, iu a novel thereof, in which a screw, O, is arranged, as

shown. Said screw passes through a socket,

N, iu which the arm P of the caster-wheel R is fixed, and when operated regulates the height of the linger-bar from the ground, the turning' ofthe screw being accomplished by a wrench put on its upper end. The out end of the socket N is made broad, somewhat in the form 'of a fan-tail, with cavities S S cut in each side thereof to receive the end of the arms of p the caster-wheel, by which means the position of the arms may be changed so as to raise or lower the linger-bar.

The screws used for raising and lowering the various parts herein referred to are held in position by means of stay blocks or pins passed through said screws, as may be most con veuient. l l

Having now described the nature and construction of ourimprovements, what we claim as our invention, and desire to secure byLetters Patent, is- ,I

1. 1n combination with the main frame, the

segmental plate a and screw b, when arranged in respect to said frame, to each other, and to the main shaft, as shown and described, for

- the purpose speced.

L 2. The screw O, in combination with the bracket I and division board or bar, and the barand platform can be raised orlowere'd, as

socket N, for the purpose of raising and lowshown and described.

ering the platform and out end of the nger- YV. P. PENN. bar, as shown and described. JACOB GEISS.

3. Making the socket N with a broad out JACOB BROSIUS. end and with cavities therein, for the purpose Witnesses: of shifting the position of the arms P of the S. G. GEORGE,
